Simultaneous effect of sdl and MoSe2 layers on CIGS solar cell performance and strategy for improving ultra-thin CIGS solar cell performance
Boureima Traore , Adama ZONGO , Issiaka Sankara , Soumaila Ouedraogo , Daouda Oubda , Marcel Bawindsom Kebre, Francois ZOUGMORE
In this paper, based on numerical simulation, the SCAPS-1D software was used to simultaneously study the influence of the surface defect layer (SDL) and the molybdenum diselenide layer (MoSe2) on the performance of the CIGS solar cell. These two defects layers are respectively formed at the front interface (CdS/CIGS) and the back interface (C(...)

Experimental study of improved cookstove with primary and secondary sources
DIANDA Boureima, OUEDRAOGO Lareba Adélaïde, COMPAORE Abdoulaye, ZONGO Wendtoin Estelle, KAM Sié and Dieudonné Joseph Bathiébo
Improved cookcookstoves are cooking devices using biomass such as wood and charcoal. Although existing improved cookcookstoves contribute to reducing wood consumption, this consumption is still considerable, and the smoke produced is a source of many illnesses. It is therefore necessary to work on further improving these "improved cookstoves".(...)

The quadratic boost is studied under its real model. The equations, of the continuous conduction mode, descriptive of this model are established. From these equations, the expressions of the voltage gain and the efficiency are extracted. These two quantities are plotted as a function of the duty cycle in order to appreciate them in different o(...)

Physical and mechanical characterization of aggregates in Burkina Faso: implications for use as endogenous knowledge in civil engineering
Abdoul Aziz Ouiminga, Adélaïde Lareba Ouedraogo, Patrice Kouraogo, Mohamed Yerbanga, Sié Kam
Aggregates are the world's most widely exploited resource, surpassing even fossil fuels. They are mainly used for concrete production. On the one hand, due to restrictions on the use of river sand in some parts of the world to conserve river beds, demand for alternative fine aggregates in the construction sector has increased considerably. The(...)
